Question 12

Thyroid cartilage protrude anteriorly

Answer 12

Adams apple

Question 13

Function of epiglottis

Answer 13

Protect superior opening of larynx not restrict passage of air to lower respiratory passage ways

Question 14

When swallowing, larynx ____

Pulled upward to prevent choking

Question 15

Trachea has _____ muscle that is lined with____
